Laboratory and Surveillance
Mosquito surveillance is an essential component of an Integrated Pest Management Program (IPM) and a considerable amount of effort is devoted to conducting adult and immature mosquito surveillance. Our program consists of locating breeding sources and monitoring mosquito populations and disease activity over time and space. We collect and analyze data on abundanceof mosquito species, we monitor distribution patterns of the different mosquito species, determine risk periods of public exposure to mosquito-borne diseases, and evaluate mosquito control activities.
We use a variety of traps for our surveillance efforts. American Light traps, which collect mosquitoes and other insects, attracted to the light produced by this trap, Mosquito Magnet® traps, which capture host-seeking mosquitoes that are attracted to the carbon dioxide produced from burning liquid propane and Gravid female traps which attract female mosquitoes that are looking to lay eggs. These traps are set in sites of all habitats throughout Sacramento and Yolo counties. Our interactive map displays the general locations of our weekly traps and how many female mosquitoes were collected during the most recent cycle.
West Nile Virus Surveillance
If the presence of these antibodies is confirmed by the California Department of Public Health laboratory there is an increased potential risk that these viruses could be transmitted to wildlife, equines or humans.
